Description
Technical field
The present invention relates to asphalt material technical field, more particularly to a kind of activated waste rubber powder modified asphalt material.
Background technology
China is tire production and automobile superpower, with the quick rise of domestic automobile owning amount, is generated every year a large amount of
Junked tire, how effectively to recycle these junked tires, prevent the pollution of the environment, be of great practical significance
With huge economic value.At present relatively conventional junked tire recovery method mainly there is prototype directly to utilize, burn heat, it is old
Tyre rebuilding, production reclaimed rubber, production vulcanized rubber powder etc. are several, wherein using junked tire production rubber powder be collection environmental protection with
The rising way of recycling that resource regeneration is integrated, is also that we advocate the optimum utilization developed a circular economy
Form.Waste-tyre rubber-powder is the flour for obtaining junked tire after mechanical crushing is handled, according to the particle diameter of rubber powder
The fields such as rubber, modifying plastics and construction material can be applied to.
The high-temperature stability of pitch can significantly be improved using junked tire powder-modified asphalt, it is low-temperature cracking-resistance, anti-aging
And durability, moreover it is possible to surface noise is reduced, reduction ground is reflective, improve skidproof effect, it is standby in high-quality ground surface material field
Concern.Obtained because rubber powder is mechanically destroyed, its internal cross-linked structure is not destroyed completely, surface molecular chain
Activity be restricted, vulcanized rubber powder is inert, the poor compatibility with pitch, it is difficult to reach satisfied technological improvement effect.《Ring
Border engineering journal》" performance of low-temperature plasma activation rubber powder modified asphalt " one text published on the 2nd phase of volume 11 in 2017
Surface activation process is carried out to rubber powder using low-temperature plasma, vulcanized rubber powder performed etching, and oxygen-containing official is introduced on its surface
It can roll into a ball so that produce physical blending and chemical reaction between rubber powder and pitch simultaneously, so that more good modified effect is reached, but
It is that low temperature plasma generation equipment price is higher, unsuitable extensive processing, and influence factor is more, treatment effect is unstable
It is fixed, using being restricted.
The content of the invention
There is provided a kind of activated waste rubber powder modified asphalt material for the defect that makes up prior art by the present invention.
The present invention is achieved by the following technical solutions：
A kind of activated waste rubber powder modified asphalt material, the modified asphalt material is useless by 100 parts of matrix pitches, 5-30 parts of activation
Rubber powder, 2-5 portions of activation palygorskites, 0.1-0.5 portions of benzaldehydes, 1-5 portions of furfural extract oils.
Described matrix pitch is asphalt, coal tar pitch or lake asphalt.
Described activation shoddy is made by following methods：By the shoddy of 50-200 mesh and treatment fluid 1 according to 1:1-2
Volume ratio input reaction vessel in, after stirring under the conditions of 40-50 DEG C stir process 2-3h, reaction terminate after filter,
Washing 2-3 times after drain, then by its with treatment fluid 2 according to 1:0.001-0.01 volume ratio mixing, stir process 20-30min,
Material is sent into baking oven by processing after terminating, and is dried to water content≤5%, is produced.
Described treatment fluid 1 be by concentration for 30% hydrogen peroxide and potassium ferrate, water according to 0.1:0.1:1 parts by weight
It is formulated.
Described treatment fluid 2 is according to 1 by silane coupler, water, ethanol:1:15-25 volume ratio is formulated.
Described activation palygorskite be by palygorskite clay in pH is 8-10 alkali lye washing after dispersed with stirring 10-15h,
Obtained after drying.
A kind of preparation method of described activated waste rubber powder modified asphalt material is：Matrix pitch is heated to 160-
180 DEG C, it is set fully to melt, later on agitating device, rotating speed is that 3500-5000 turns/min, then will activation shoddy, work
Changing palygorskite, furfural extract oil, equivalent is added in three times, and total time control is 40-60min, is eventually adding benzaldehyde, continues to stir
The material is produced after mixing reaction 20-30min.
Compared with prior art, the present invention is first aoxidized with hydrogen peroxide/potassium ferrate combined oxidation system to shoddy
Processing, makes its surface expose substantial amounts of active group, processing is modified to it followed in turn by silane coupler hydrolyzate, is reached
To highly efficient active effect, the shoddy and the compatibility of matrix pitch so obtained more preferably, so as to improve compound drip
The performance of green material；In addition, activation palygorskite can not only improve the temperature tolerance and ageing resistance of composite asphalt material, moreover it is possible to inhale
The waste gas grown nonparasitically upon another plant during producing, reduces dirt, and under the cross-linking catalyst effect of benzaldehyde, the ductility of composite is had
Effect, waste gas burst size is further controlled, and the modified asphalt material of preparation has excellent performance and the feature of environmental protection, economic value concurrently
It is higher.
